The depletion region in a semiconductor p-n junction diode has Positive and negative ions on either side.

Here's why:

1. A p-n junction diode is formed by doping one side of a semiconductor material with a p-type dopant (which creates an abundance of holes) and the other side with an n-type dopant (which creates an abundance of electrons).

2. When the p-n junction is formed, free electrons from the n-region start to combine with the holes in the p-region. This is called recombination.

3. As the electrons move across the junction from the n-region to the p-region, they leave behind positively charged ions in the n-region. Similarly, as the holes move from the p-region to the n-region, they leave behind negatively charged ions in the p-region.

4. This movement of electrons and holes across the junction creates a region on either side of the junction that is depleted of charge carriers (i.e., it has no free electrons or holes). This is called the depletion region.

5. Therefore, the depletion region in a p-n junction diode has positive ions on the n-side and negative ions on the p-side.
